Webrecently, greedy algorithms such as the subpace pursuit(SP) [7] and the compressive sampling matching pursuit (CoSaMP) [8] have been proposed by incorporating the idea of backtracking. They offer com-parable theoretical reconstruction quality as that of the LP methods and low reconstruction complexity. However, both the SP and the WebAfter that, it compares the reconstruction algorithm of FH-BPSK signals of compressive sampling and sparsity. It also discusses the reconstruction algorithm and its improvement of SL0 (Smoothed L0 Norm) and compares it with the classical OMP (Orthogonal Matching Pursuit) algorithm.
